LV's are similiar to partitions and when using the Logical Volume manager you can manage and change the volumes much easier then using a partition and partition tools.
|
|
|
Maximum Partitions.
|
4 Primary partitions and 15 total.
|
|
|
Typical Disk Setup
|
3 Primary Partitions and 1 extended that can hold many Logical Partitions
|
|
|
LVM Solves the issue of Extended Partitions by
|
Allowing you to create many file systems within a single partition in a more elegant way.
|
|
|
Namespace
|
a Unique set of names or Identifiers.
|
|
|
Absolute Path name

|
Swap Partition
|
Linux temporarily stores programs and data on swap when it does not have enough ram. Also used when hibernating.
|
|
|
Recommended Swap size
|
One and two times the amount of ram in your system. Minimum size is 256mb.
|
|
|
Worst case Hibernation swap size.
|
One and Half times the size of ram.
|
|
|
is Swap required?
|
No but systems tend to perform better with one.
|
|
|
Is a swap partition mounted?
|
No and it not associated with a mount point.
|
|
|
/Boot
|
Hold the kernel and other data the system needs when it boots. Cannot be under a LVM.
|
|
|
Size of /Boot
|
Typically is 200mb and can be as small as 50mb.
|
|
|
Reccomended /Boot size for Fedora.
|
300mb
|
|
|
Easy older system /boot compliance.
|
Make /boot one of the first partitions on the disk.
|
|
|
/var
|
Data changes frequently. Holds system logs, package information and accounting data.
|
|
|
/var size
|
500mb and up! As much as needed. Good idea to make /var a separate partition.
|
|
|
Recommended filesystem for /boot
|
ext2 because the data does not change frequently.
|
|
|
/home
|
Ideally should be put into own partition to make reinstalls easier and less risky.
|
|
|
size of /home
|
As large as neccesary.
|
|
|
/usr
|
holds installed packages. Size can be from 2-16gb depending on how much you install.
|
|
|
RAID stands for
|
Redundant Array of Inexpensive/Independent Disks.
|
|
|
Raid employs
|
Two or more hard drives in combination to improve fault tolerance and OR performance.
|
|
|
Raid is seen as
|
a single logical device.
|
|
|
T or F Raid is a good backup plan?
|
False
|
|
|
Raid 0
|
Striping, No redundancy.
|
|
|
Raid 1
|
Mirroring
|
|
|
Raid 5
|
Striping with Parity
|
|
|
Raid 6
|
Striping with Double Parity. Inefficient with a small number of drives.
|
|
|
Raid 10
|
Raid 1 + 0 = Raid 10. Requires 4 Disks.
|
|
|
MBR=
|
